|
A = |
|
Floor to Clavicle. Easy way to get "C". Torso measurement. To determine the top tube length. |
|
|
B = |
|
Crotch to ground measure. To determine seat tube height. |
|
|
C = |
|
Crotch to Clavicle. Part of Torso measure. To determine top tube length. A-B= C |
|
|
D = |
|
Thigh (femur) length. Hip joint to Knee joint. Helps determine seat position |
|
|
E = |
|
Lower leg length. Knee joint to ankle joint. Helps determine seat position |
|
|
F = |
|
Shoulder width. Needed for handle bar size. |
|
|
G = |
|
Over all arm length. With the arm straight out from the body. Measure from shoulder joint to wrist joint. Helps for seat to handle bar positioning. |
|
|
H = |
|
Lower arm length. Helps for seat to handle bar positioning. |
|
|
I = |
|
Shoe size |
|
|
J = |
|
Weight |
|
Best way to measure "B" is to put a hard-backed book firmly between your legs, such that it simulates the bike seat. Try to keep the book parallel to the floor. Measure from the ground to the book edge, which is closest to the pelvis bone.
We use these measurements to help determine the correct frame size and to determine head stem length and handle bar position. We take your old frame data if available and design the frame. Then we create a stick person based on these dimensions to determine if we have a good fit to the frame and then modify the frame dimensions to fit the body.
